Beschreibung
Zusammenfassung:	The invention relates to the field of ceramics and open-celled silicon carbide foam ceramics, which can find application, for example, as high temperature- and thermal shock-resistant silicon carbide foam. The aim of the invention is to disclose an open-celled silicon carbide foam ceramic with improved thermal shock resistance, which may be produced by a simple method. Said aim is achieved with an open-celled silicon carbide foam ceramic, the structure of which is made up of sintered silicon carbide with a 5 to 30% pore volume of closed pores with an average diameter of 1800° C. under a protective atmosphere or in vacuo.
